Let us imagine, for sake of argument, we are trying to solve a crossword clue. To make the analogy more apt, let us say it's imperative to do this puzzle. There's a prize if we get it right or a punishment if we fail. 'Any old word' won't do. The object of the exercise is not just to fill space. We're better off with a hole in our grid than with a misleading answer. And we may not know what to accept but we know what to reject. That's a fine start. Perhaps we should be fussy, bold and be ready for anything.....Theory and practice are two very different things. Sometimes, there's simply no substitute for experience. We may well decide that there's no point in sitting around looking at the map a moment longer. The only way to get from A to B is to pick up our feet and start walking and to cast our caution to the winds. Put our money where our mouth is. Show the world that we mean business. The details of the route will sort themselves out if we just begin to move our feet!!!! (only if it was that simple!)
